Leaking flat roof in Belvidere? Call (862) 318-3997 and tell us whether the water is under the addition, a porch roof or the main house.
A rear addition is the usual one, sometimes an enclosed porch roof or the dead-flat run over a back kitchen. Those sections hold water where the main roof sheds it, and their seams tend to give out well before the shingles out front do.

Who Signs Off on the Work in Belvidere
Permitted work on a Belvidere roof is inspected and signed off through the Belvidere building department, not by anyone in Clifton. Resealing a seam or re-flashing a drain is ordinary repair and usually needs no permit. Where a membrane replacement requires a permit, confirm in the written estimate who files it and books the inspection.

Where to Find Flat Roofs on a Belvidere House
Belvidere sits on the Delaware and takes up under a square mile and a half. In it, a house with an older main block usually got its flat roofing later.
Check the back for a rear addition, an enclosed porch, or the low-slope run over a mudroom. Mostly the material is EPDM rubber or torch-down.
A good many of these roofs have been patched, often with caulk or a material unlike the roof around it.

The Warranty on a Belvidere Roof
On a Belvidere roof, a 2-year warranty covers repairs and a 50-year warranty covers replacement. NJ HIC #13VH11720500 is our registration, and the company is licensed and insured. The roofer who inspects your membrane and writes the number also comes back to weld the patch.
The Pitched-to-Flat Transition, Done Right
On any Belvidere house with an addition, check the joint where a steep main roof drains onto the flat section. The whole pitched roof empties onto a few feet of membrane there. The flashing at that wall was often done cheaply when the addition went up.
We rebuild it as one detail. Counter-flashing goes into the shingle side, and the membrane is turned up the wall far enough that the pitched flashing laps over it.
On the homes inside the Belvidere Historic District, this transition takes extra care. Greek Revival and Victorian rooflines are complex, with valleys and dormers sending water toward those flat sections. We flash and seal that line for the volume of water it carries.

How We Trace a Leak Instead of Guessing
1. Walk the Whole Membrane
We map every penetration, the seam condition, and the ponding before touching a thing.
2. Find the True Entry
The wet spot inside is rarely under the hole.
3. Repair in Kind
EPDM gets EPDM detailing and TPO gets a weld, matching the system you already have.
4. Prove the Drainage
We check the way water leaves so that the patch holds.
